TDS above 1000 78% rejection rate post TDS 262
Hi all,
Looking for advice from those in the States that live in areas with high a very TDS.
Bit of background, I'm from the UK but now live in Spain. The water here can fluctuate a lot. Last year it was around the 500 mark and I was getting a TDS low enough to breed in.
This year I'm using a 400g RO and I'm getting a TDS of 262. I'm going to look into our PSI and I will add a booster pump but I've seen in India that they have RO membranes specifically made for TDS above 1000.
I have over 14 pairs of discus looking at me asking what the hell's going on so if anyone is aware of any RO membranes in the States that deal with a high TDS please can you let me know.
Kind regards
Lee

A TDS of 262 sounds like a defective membrane. Even at 1000 TDS and a not so good rejection rate of 5%, that should output a TDS of 50.
What RO system and membrane are you using?
